The Continental morphotype of tall fescue is one of the main forage and turf grass species. However, it suffers from summer drought, especially in dry and hot climates. On the other hand, the Mediterranean morphotype of tall fescue display summer dormancy. Hybridization of the two morphotypes seems...
